This invention relates to closures for non refillable bottles and has for its object to pro- 'vide a-closure of this kind having no complicated valves and no cap embracing the bottle neck.

The closure is particularly simple in construction and consequently verycheap to manufacture.

In the accompanyin drawing several constructional examples of the closure according to the invention are shown diagrammatically, Figures 1 and 2 being vertical sections through two constructional forms, having no movable parts, and Figure 3 a corresponding cross-section, Figures 4 and 5 vertical sections through two constructional forms with quite simple valves, for which Figure 3 can also be taken as representin a cross-section, without showing the valves, owever.

Referring to Figures 1 to 3, in the bottle neck 1 a cork ring 2 or someother packing is provided. Inside the-said corkring is an annular dished member 3, suitably made of porcelain, the inner rim of which in the form shown in Fig. 1 is lower than the outer rim, while in Fig. -2 a second cork ring 4 or the like is provided for keeping the second insertion to be referred to below at a suitable distance from the inner rim of the dished member 3. The second insertion 5 just referred to, which rests on the outer rimof the dished member 3 or on the said second ring, isprovided with an inner cylindrical extension 6 which forms an inverted dished member below the extension and projects into the an nular space in the dished member 3, without being in contact with the walls of the same. From two oppositely located ,points of the insertion 5, inclined passages 7 and 8 extend upwards in such a manner that they commence outside the cylindrical extension 6 and open in a vertical bore or recess 9,,provided in the upper part of the insertion 5. In Figsage 7 enters it from below. 'A cork-rin 10-is inserted in the recess 9 for holding the spout or outlet proper 11. The other; pas sage 8 opens above t e cork ring 10 and communicates there with the outer air. According to Fig. 2 the two passages 7 and 8 open ure 1 this opening 9 is eccentric and the pas 213,128, and .in Germany September 6, 1926.

into the bottom of the recess 9 and in the spoutll opposite the outlet opening is an air vent 12. a

After the bottle has been filled the parts 2 to 9 referred to are inserted, the spout being in the meantime replaced by a cork stop r. The spout is only inserted when the bott e is to be used. If the bottle be then tilted when pouring out, the liquid passes out through the" lower lying part of the dished member 3, the passage 7 and the spout 11-, while air enters through the air vent 12, the passage 8 and the higher lying part of the dished member 3. If, after the removal of the spout 11 and stopping up one of the two passa es 7 or 8, an attempt be made to pour in liquid, this 1 will be found impossible, as the liquid in the dished member 3 prevents the escape of air and the entrance of liquid.

If desired, additional safety means covering the inner opening in the inserted part 3 may be provided, as shown in Figures 4 and 5. In the arrangement shown 1n Fig. 4- a valve pin 14 provided with a top plate or cone 13 is inserted in the said opening, the lower end of which is suitably thickened for increasing its weight to a certain extent. In the constructional form shown in Fig. 5v the cylindrical extension 6 is omitted from the insertion 5 and in its place an inverted dished 80 member 15 is provided, which when in the position of rest, covers the said opening.

The bottle closure and the bottle to be used with it may be made of any suitable material, for instance,=of metal. The cork rings 2 and a5 4 could then be replaced by screwing, riveting, bolting or the like. Similarly with glass or .porcelain bottles, the ork rings 2 may be replaced by fluted, roughened and cemented parts, as indicated in Figure 2. What I claim is:

1. A closure for non-refillablebottles comprising in combination an annular dished member inserted in the neck of the bottle, said 7 member having an upwardly extending in- 9 ner rim, an outer closing member inserted in the neck of thebottle above said annular dished member, an inverted dished member below the said closing member and extendmo ing downwardly into the said annular dished member over the inner rim thereof without touching the walls of the dished member, passages in said outer closing member, extending upwardly therein from the partof the bottom thereof outside the said inverted 5 dished member, for allowing the escape of liquid from the bottle and the admission of air therto when pouring out the contents of the bottle, the inverted dished member below said closing member being adapted to coact with-said upwardly extending inner rim so as to trap a quantity of liquid in the annular dished member, sufficient to prevent liquid being poured into the bottle, through said passages, as set forth.

15 2. A closure for non-refillable bottles as claimed in claim 1, and comprising a valve capable of resting on the inner rim of the annular dished member and closing the middle opening of the said annular dished mem- 2 her when the bottle is upright and of being raised from said inner rim so as to uncover the said middle opening, when the bottle is tilted for pouring out the contents, as set forth.

In testimony whereof I have signed my name to this specification.

ALFRED HAFERMANN.
